Isometric ContractionIsolate a wide range of muscle groups and evaluate theirisometric contraction characteristics for performancequantification. Configure the TSD121C handdynamometer to measure handgrip force or a wide rangeof pulling forces. To measure pulling forces, secure thedynamometer to a fixed surface, then connect a tetherbetween the dynamometer and the muscle group underinvestigation. If the exerted force will exceed 100kg, usepulleys to attenuate muscle forces to less than 100kg. Foradditional insight, acquire EMG data during isotonicforce measurement.Isotonic ContractionExamine muscle groups for isotonic performance byplacing the TSD109 accelerometer on a target limbactively hoisting weights of specific sizes. Theaccelerometer records the precise time the weight moves,and the subsequent acceleration of that movement. Forisometric to isotonic transition investigations, use theTSD121C Hand Dynamometer with the Dynagripsoption. Place the dynamometer in-line between theweight to be hoisted and the target limb. As the weightis lifted, the hand dynamometer will measure the appliedlifting and transition forces, while the Accelerometerindicates the transition timing.Ergonomics EvaluationBody position and posture can be analyzed over awide range of static and dynamic conditions and thesemeasurements can be used to determine the ergonomiccharacteristics of a specific work activity orenvironment. To reliably record head tilt with respectto the X-, Y- and Z-axes simultaneously, place a TSD109accelerometer on the head. To directly measure adequatebending in the knees or unsafe rounding in the lowerspine, use goniometers.Synchronize with Video CaptureThere are several ways to synchronize motion analysisequipment employing video capture with the MPSystem.1) The video capture system can send a TTL triggerstart pulse to the MP System.2) The vertical sync pulse from the camera can bedirected to an unused analog input and thenAcqKnowledge’s peak counter can compare theexact video recording time to the other datachannels recorded by the MP System.3) The MP System can send a synchronizing trigger tothe video capture system.Remote MonitoringFor biomechanical measurements, the recording cablesattached to the subject must be durable but unobtrusive.The TEL100C remote monitoring module set supportsan extremely wide range of biomechanical measurements,with minimal cable hindrance and maximal motionflexibility. With the appropriate Smart Sensor, theTEL100C can perform the same recordings asstandard amplifiers and transducers when using an MPSystem. The TEL100C can be located up to 60 metersfrom the recording computer—data is transmitted tothe MP System using a single, lightweight, coaxialtransmission cable. Each TEL100C will amplify upto four channels of data and the input channelsautomatically configure themselves for the type of SmartSensor plugged into the amplifier/transmitter.
